How do I acquire on a second analog channel while waiting indefinitely for an external gate on another?

[zlma]

I would like to repitively acquire every two seconds on one analog DAQ channel (ch5) and simultaneously acquire on a second analog (ch7) channel that hangs indefinitely for an external trigger.  Is there a way to do this?

I'm currently running the acquisitions from two different VI's.

I currently get the following error:

"

Error -50103 occurred at DAQmx Start Task.vi:5

Possible reason(s):

NI Platform Services:  The specified resource is reserved. The operation could not be completed as specified.

Task Name: _unnamedTask<84>

No, you cannot do that with a single device. Both channels have to be in the same, single task.
